Application filed February 7, 1916. Serial No. 76,685.

To all whom it may concern Be it known that l, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Oak Farlgin the county of Cook, State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a description, reference being bad to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements insewing machines, and more particularly to a sewing machine wherein the material being stitched is supported by a work supporting arm extending at an angle to the plane of the overhanging arm of the machine.

An object of the invention is to provide a machine of the above character with a horizontal arm supported by the standard on which is carried the work supporting arm proper, and in which horizontal arm is.

mounted the main shaft of the machine, suitable. devices being operated by said main shaft for actuating the needle and the complemental stitch forming mechanism.

Another object of the invention is to provide a machine of the above character wherein the needle may be reciprocated by an scillating shaft in the overhanging arm which in turn is oscillated by the main shaft.

A further object of the invention is to pro vide a machine of the above character having an oscillating shaft for reciprocating the needle with a thread laying device which is also oscillated by said shaft in the overhanging arm.

A still further object of the invention is to provide a machine of the above character having a shaft in the overhanging arm for oscillating the needle and the thread laying device with a trimmer wherein the movable blade operates in a horizontal plane, and said blade is oscillated through a train of connections actuated by said oscillating shaft in the overhanging arm.

El still further ob 'ect of the invention is to provide a machine of the above character having the main shaft in the horizontal arm with theloopcr andthe feeding device which are carried by the work supporting arm proper and which are actuated by said main. shaft in the horizontal arm.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

The machine embodying my invention consistsbroadly of a supporting standard from which projects an overhanging arm carrying the needle bar and needle, also the thread laying device which cooperates with the needle and the trimmer which trims the fabric in advance of the stitching point. These parts are operated by an oscillating shaft located in said overhanging-arm. The standard also carries a forwardly projecting arm on which is mounted a horizontal arm' carrying the main shaft, said main shaft extending through the projecting arm on the standard, and carrying a belt wheel on its outer end. At the free end of the horizontal arm there is a supporting post on which is mounted the work supporting arm proper. This work supporting arm is'arranged at an angle to the plane of the overhanging arm and has its free end extending underneath the free end of the overhanging arm. A looper cooperates with the needle and is located in said work supporting arm. Feeding-devices are also located in the work supporting arm. These feeding devices and the looper are operated from the main shaft located in said horizontal arm.

Referring more in detail to the drawings,

-my improved machine consists of a supportoverhanging arm and extends into the standard. Projecting laterally from the standard and forwardly from the standard is a supporting arm 5 which carries a horizontal arm 6. This horizontal arm is substantially parallel with the overhanging arm 3. At the outer end of the horizontal arm 6 there is a depending post 7, and this depending post carries at its lower end the work supporting arm 8. Said Work supporting arm 8 extends at an angle to a vertical plane containing the longitudinal center of the overhanging arm, that is, the plane of the overhanging arm, and the free end of this work supporting arm 8 terminates underneath the outer end of the overhanging arm 3.

Mounted in the horizontal arm 6 is a main shaft 9. This main shaft extends through a bearing 10 at one end thereof and through bearings 11 and 12 adjacent the other end thereof. Said shaft projects through the arm 5 and is provided with a belt wheel 13. Said shaft 9 is formed with a crank 14 and a pitman l5 cooperating with the crank oscillates the shaft 4: in the overhanging arm. Said shaft 4 has a depending arm 16 to which the pitman 15 is connected by suitable means.

Mounted in the outer endof the over I is formed with a counterweight 21, which. counterbalances the parts operated by the arm 19 and prevents unnecessary vibrations when the shaft 4 is oscillated rapidly.

. At the lower end of the needle bar 17 there are two pairs of needles 22 and 23. These pairs of needles are staggered relative to each other, as clearly indicated in Fig. 8 of the drawings. The material to be stitched is held on the work supporting arm 8 by a presser foot 21 which is mounted on the lower end of a presser bar 25, and this presser bar is in turn mounted to slide in suitable bearings inthe overhanging arm 3. The presser foot is provided with suitable needle slots 26 and 27 which receive respectively the pairs of needles 22 and 23.

inseam/a at cross threads for the needles are guided by a fixed thread guiding arm 28, said arm hav ing a thread eye 29 through which the thread passes and a second thread eye 30 through which a thread d passes- There are two thread hooks 31 and 32.

- The thread hook 31 as it moves forward engages the thread 0 and positions the same, as shown in Fig.- 16, so that the left hand needle 22 will pass between the strands of the loop formed by the thread hook 31, While the right hand needle 22 passes in front of said thread. This causes the thread 0 to be stitched down by the needle threads a-a and to be woven back and forth passing around the needle threads at each needle puncture, as

clearly shown in Fig. 15. The thread. hook 32 cooperates with the needles 23. This thread hook engages the thread al and operates thereon in precisely the same manner as above described in connection with the hook 31. The threadhooks 31 and 32 are carried by a supporting arm 33. Said arm has an enlarged head 34: at its lower end and the thread hooks are separately connected thereto so that they may be properly adjusted. Said supporting head 34 is provided with thread guiding eyes 35 and 36 through which the threads 0 and d pass respectively.

The fixed thread guiding arm 28 is attached to the overhanging arm by suitable till means. The supporting arm 33 is carried by a collar 37. which is rigidly secured to a sleeve 33, see Fig. 10. y The sleeve 38 is mounted on the presser bar 25. The opening in the overhanging arm at the lower end for the presser bar, as shown in this figure,is enlarged so as to permit the sleeve 33 to ex tend down through the opening. Said sleeve is formed with a shoulder 39 which rests on the upper face of the lower bearing of the presser bar.

The sleeve 33 is formed with a projecting arm 40, see Fig. 13. This'sleeve is oscillated by a rock lever il which has a depending arm 42 carrying a ball stud 43 and a link 44: engaging this ball stud also engages a ball stud 45 on the outer end of the arm 40. The rock lever a1, as shown in Fig. 7, is mounted on cone bearings 46 and 4-7 carried by a supporting rod 48 which extends through a portion of the overhanging arm and is rigidly secured thereto by a clamping nut 43. The other arm lt) of the rock lever 41 is connected by a link 50, see Fig. 6, to an arm 51 mounted on the shaft 4-. The oscillations of the shaft 4 will rock the lever ail and this will. through the link 4-4, oscillate the sleeve 33 which will in turn oscillate the supporting arm 33 and the thread hooks carried t iereby.

In order to trim the edges in advance of the stitching, T have provided a trimming mechanism which includes a fixed. trimming blade 52 and. a movable trimming blade 53. The fixed trimming blade is mounted on the the auxiliary 54 swings about a vertical axis and thetrimming blade 53 moves'in a horizontal plane. This trimming mechanism operates to trim the edges of the fabric sections after which they are abutted, as referred to above.

The arm 54: carrying the trimmer blade is fixed to the lower end of the auxiliary guiding bar 55. This auxiliary guide bar operates to guide the main presser bar 25 and prevent the same from oscillating. This is accomplished by an arm 56 which is fixed to the presser bar25 by a setscrew 57. Said arm projects rearwardly and is provided with an opening 58, see Fig. 14, through which the auxiliary guiding bar freely passes. The arm 56 is formed in its upper face with a circular channel 5'? into which extends an inverted cup 58. This channel fits the cup loosely. A spring 59 encircles uide bar 55 and rests at its lower end on t e upper face of this cup. A threaded sleeve 60 extends through the upper bearing 61 for the auxiliary guide bar 55 and the spring 59 at its upper end bears agalnst this threaded sleeve 60. By turning the sleeve down or up, the tension of the spring on the arm 56 may be varied. This spring 59 places a tension on the presser bar, that is, normally holds the presser bar against the work support. The auxiliary guide bar 55 not only passes freely through. the arm 56, but also through the inverted cup 58 and the sleeves 60 so that it is free from any endwise pressure and may also oscillate freely in these parts. A spring 62 encircles the auxiliary bar 55 and bears at its lower end against the arm 54:. The upper end of this spring 55 bears against a washer 63 in a recess in the lower face of the lower bearing 64 for the auxiliary guide bar. This spring 62 normally forces the guide bar 55 down wardly and holds the movable trimming blade 53 in contact with the stationarv trimming blade. y

The auxiliary guide bar is provided with a collar 65 whichcarries an arm 66. see Fig. 11. An eccentric 67 is fixed to the upper end of the sleeve 33. An eccentric strap 63 cooperates with this eccentric and engages a ball stud 69 at the outer end of the arm 66. This eccentric 6? is in the form of a segment of a sphere and therefore, the auxiliary bar 55 may have a limited movement in a vertical direction without interfering with the connection with said eccentric. This permits the presser foot to be raised and lowered and the movable trimmer blade to maintain its operative position relative to the presser foot.

From the above description, it will be apparent that the shaft l located in the over hanging arm through the arm 13 recipro cates the needle arm 17 and through the arm lllld llllh 51 and the rock lever 41 oscillates the sleeve 38. The oscillations of this sleeve 38 are imparted directly to the thread laying hooks and through the eccentric 67 said oscillations impart .movement to the auxiliary presser bar and thus to the movable trimming blade.

The main shaft 9 projects into the sup-' porting post 7 and carries actuating devices for the looper and for the feeding mechanism. As hereinshown-the horizontal arm 6 has an overhanging portion 70, while the post 7 is provided with a laterally pro'ecting portion 71. These parts 70 and 1 are formed with projecting 1ugs72, and suitable bolts 73 pass into the lugs and secure the sections together, and in this manner the post 7 with the work supporting arm proper is carried by the horizontal arm 6. This construction is shown in detail in Figs. 2 and 4. The looper 74 cotiperates with the front pair of needles 22, while the looper 75 cooperates with. the" rear pair of needles. These loopers are mounted on a looper carrier 76, see Fig. 17, and the looper carrier is fixed to a looper supportin shaft 77 This looper supporting shaft 77 is mounted in suitable bearings 78 and 79 so that the shaft may not only oscillate but be moved endwise in the bearings. The looper supporting shaft 77 is oscillated by a trainof mechanism connected to the main shaft 9 in the horizontal arm 6. Said train of mechanism consists of an arm 80 carried by a collar 81 fixed to the shaft,a rock shaft 82 which carries'an arm 83 and this arm 83 is connected to the arm a link 84. The arms 80 and 83 are formed with ball studs so that the shaft 77 may have an endwise movement without disturbing its connection with the rock shaft 82. The rock shaft 82 is provided with a second arm 85 carrying a ball stud and an. eccentric strap 86 cooperating with an eccentric 87 on the main shaft 9 engages this second arm 85. As the main shaft 9 rotates, the eccentric 87 will oscillate the rock shaft 82, and this in turn through the arms 80 and 83 and the connecting link 84 will oscillate the looper shaft.

The looper shaft is moved endwise by a sleeve 88. Said sleeve is freely mounted on the shaft and is located between fixed collars 89 and 90. This permits the shaft to oscillate 'in the sleeve, but any endwise, movements of the sleeve will be imparted to the shaft. Said sleeve 88 has a downwardly projecting fin 91 which extends between guide plates 92 and holds the sleeve from oscillating. The sleeve 88 is given an endwise movement by a rock shaft 93. Said rock shaft has a downwardly; projecting slotted arm 94 and a link'95 has an adjustable connection with the slot inthe arm 94; and is also connected to the sleeve 88. This shaft 93 on its other end carries an arm 96, see.

Fig. 18. On the'outer end of the arm 96 is a ball stud97 with which an eccentric strap 98 I connects. This eccentric strap 98 cooperates with an eccentric on the main shaft 9, see Fig. 5. This eccentric strap will oscillate the rock shaft 93 which will move the collar 88 endwise, and this gives the endwise move ment to the looper supporting shaft.

. For moving the work along the arm there is a main feed dog 99 which. is fixed to a feed bar 100. This feed dog is so constructed as to feed the work off the end of the arm. The feed bar 100 is connected to a sleeve 101 which receives an eccentric 102 fixed to the main shaft 77. The eccentric 102 may move endwise in the sleeve or the sleeve endwise on the shaft. The oscillating movements of the shaft will, however, through the eccentric raise and lower the sleeve 101. The feed bar adjacent its rear end is supported by a cross pin 103. The cap plate 104 is formed with a recess which provides a slot 105 for this pin 103. This permits the feed bar to move endwise on the pin, but said pin serves as the fulcrum for the feed bar so that as the sleeve 101 is raised and lowered the feed dog will be raised and lowered. Said feed bar is moved endwise by a link 106 which is pivotally connected at 107 to the end of the feed bar. The other end of this link 106 is pivotally connected to a stud 108 which is auxiliary feed dog 111 which is carried by an auxiliary feed bar 112. The main feed bar 100 is slotted lengthwise to receive this auxiliary feed bar, and said auxiliary feed bar is slidingly held in said slot by a screw 113 passing through a slot in the bar. The

auxiliary feed bar will be raised and lowered in timing with the main feed bar. This auxiliary feed bar is moved endwise by a mechanism which permits it to have a differential movement relative to the main feed bar.

Mounted in the work supporting arm 8 is a U-shaped lever 114. The feed bars and the looper shaft pass between the arms of this U-shaped lever. Said U-shaped lever is mounted to oscillate on a supporting pin 115. The arm 116 of said U-shaped lever is connected at its upper end to a link 117, and this link is in turn connected to the auxiliary feed her 112. When the parts are ositioned as shown in Fig. 19, the stud 120 13 substantially opposite the pivotal connectionhetween thelink 117 and the arm 116. As" the main feed bar moves back and forth, the link 121 will oscillate the U- shaped lever 114 and the oscillations of this U-shaped lever will, through the link 117,

work supporting arm proper.

till

ltd

raaaara auxiliary feed dog will be substantially the same as that imparted to the main feed dog.

If this stud 120 is shifted downwardly in the slot 119, then the amount of movement im} parted to the auxiliary feed bar relative to the amount of movement imparted to the main feed bar will be increased. The link 121 may be shifted by a hand lever 123 which is connected by a link 124: to the link 12].; This hand lever may be provided with a finger piece 125 which is located outside of the work supporting arm so that the lever ma be readily shifted.

lit will loope'r cooperates with each pair of needles, the needle loops beneath the sections of fabric being joined being connected by the looper threads. The abutted edges of the fabric sections are, therefore, joined by the cross threads on the upper face-of the fabric and the looper threads on the lower face of the fabric.

From the above description it will be apparent that l have provided a sewing machine having a. suspended work supporting arm located at an angle to the plane of the overhanging arm, and the fabric sections being stitched are fed od fromthe end of this work supporting arm. The main shaftfor operating the parts is located in the horizontal arm which supports this work supporting arm, and the needles, the trimmer and the thread laying devices are operated from one end of this main shaft, while the looper and feed are operated from the other end of the main shaft. This arrangement has a special advantage in the type of ma chine-where there is a forwardly projecting arm carried by the standard, a horizontally disposed arm mounted on this forwardly projecting arm and in turn. supporting the In other words, between the end of the main shaft and the looper shaft there is a train of connections of substantially the same extent as the train of connections between the other end of this main shaft and the oscillating shaft which vibrates the needles and operates the other elements carried by the overhanging arm. This clearly distributes the strain on the main shaft and avoids long trains of connections which, of course, are objectionable. I

The looper mechanism described above 1s shown, described, and claimed in my copending application 83,297, filed March 10, 1916/ The thread laying mechanlsm 1s described. and claimed in my copending application Serial No. 83,300, filed March 10, 1916. The trimming mechanism is described and claimed in my copendlng apbe understood, of course, that a plication, SerialNo. 83,299, filed'March 10, 1916. The feed mechanism is described and claimed in my copending application, Serial No. '83,298,'filed March 10, 1916.

These devices above described are, therefore, not claimed per 86 in this application, as they form no part of the present invention, except as they are elements of the combinations set forth in the appended claims.

It will be understood that various changesin the arrangement of parts and modifications in the details of construction shown and described may be made Without departing from the spirit of this invention as set forth in the appended claims.
